Description
Diese Erfindung bezieht sich auf ein Gerät zum Transportieren kryogener Flüssigkeiten, insbesondere aber nicht ausschließlich auf Straßentankfahrzeuge.These The invention relates to a device for transporting cryogenic Liquids, in particular but not exclusively on road tankers.
Die Verwendung von vakuumisolierten Tankfahrzeugen zum Transportieren kryogener Flüssigkeiten ist gut bekannt. Jedoch sind solche Tankfahrzeuge gewöhnlich für die Beförderung einer einzigen Flüssigkeit wie beispielsweise Stickstoff, Sauerstoff, Argon oder ein vorgemischtes Gas ausgelegt. Da solche Tankfahrzeuge für den Transport einer beträchtlichen Menge einer kryogenen Flüssigkeit ausgelegt sind, sind solche herkömmlichen Tankfahrzeuge natürlich dann ineffizient, wenn nur kleine Mengen verschiedener kryogener Flüssigkeiten geliefert werden sollen, oder wenn Gasgemische mit verschiedenen Zusammensetzungen geliefert werden sollen.The Use of vacuum-insulated tank vehicles for transport cryogenic fluids is well known. However, such tank trucks are usually for transportation a single liquid such as nitrogen, oxygen, argon or a premixed Gas designed. As such tankers for the transport of a considerable Amount of a cryogenic liquid are designed, are such conventional Tank vehicles, of course then inefficient, if only small amounts of different cryogenic liquids should be supplied, or if gas mixtures with different compositions should be delivered.
Aufgabe der vorliegenden Erfindung ist es, ein Gerät zum Transportieren kryogener Flüssigkeiten zu schaffen, das die oben erwähnten Probleme bewältigt.task The present invention is a device for transporting cryogenic liquids to create the above mentioned ones Overcome problems.
Ein
solches Tankfahrzeug nach dem Oberbegriff des Anspruchs 1 ist aus
dem nächstkommenden
Stand der Technik der
Gemäß der vorliegenden Erfindung ist ein Tankwagen zum Transportieren von kryogener Flüssigkeit so gesehen, der einen isolierten Behälter aufweist, der innen durch mindestens eine Membran in mindestens zwei Teile unterteilt ist, wobei jeder Teil zur Aufnahme einer kryogenen Flüssigkeit dient, wobei die Membran aus einem Material mit ähnlichen Wärmedehnungseigenschaften wie demjenigen des Behälters gebildet ist, und wobei Mittel zum Aufrechterhalten eines im wesentlichen gleichen Drucks in jedem Teil vorgesehen sind.According to the present Invention is a tank truck for transporting cryogenic liquid seen in this way, which has an insulated container inside at least one membrane is divided into at least two parts, wherein each part serves to receive a cryogenic liquid, wherein the membrane made of a material with similar thermal expansion properties like that of the container is formed, and wherein means for maintaining a substantially equal pressure are provided in each part.
Bei einer solchen Anordnung können zwei oder mehr verschiedene Kryogene durch einen einzigen Tankwagen transportiert werden und die Unterteilung des inneren Tanks des vakuumisolierten Behälters durch eine Membran oder Blechmaterial mit ähnlichen Wärmedehnungseigenschaften wie denjenigen des Behälters stellt sicher, daß im Betrieb keine Leckage an der Dichtung zwischen den peripheren Rändern der Membran und dem Behälter stattfindet. Der Umbau eines Standard-Kryogentankwagens in einen Tankwagen nach der vorliegenden Erfindung ist eine relativ einfache und billige Angelegenheit, die nur die dichtende Befestigung der Trennmembran(en) innerhalb des Behälters und das Vorsehen von Abgabemitteln zur Abgabe kryogener Flüssigkeit aus jedem Teil des Behälters erfordert, wie nachstehend noch beschrieben wird. Das Vorsehen von Mitteln zum Aufrechterhalten eines im wesentlichen konstanten Drucks in jedem Teil ist vorteilhaft, da es dadurch möglich ist, die Membran so dünn und daher so leicht wie möglich auszubilden, entsprechend der Anforderung an die Undurchlässigkeit.at such an arrangement can two or more different cryogens through a single tanker be transported and the subdivision of the inner tank of the vacuum insulated container through a membrane or sheet material with similar thermal expansion properties as those of the container make sure that in Operation no leakage at the seal between the peripheral edges of the Membrane and the container takes place. The conversion of a standard cryogenic tanker into one Tank truck according to the present invention is a relatively simple and cheap matter, only the sealing attachment of the Separating membrane (s) within the container and the provision of Delivery means for discharging cryogenic liquid from each part of the container requires, as will be described below. The provision of Means for maintaining a substantially constant pressure in each part is advantageous because it is possible, the membrane so thin and therefore so as easy as possible according to the impermeability requirement.
Transportbehälter für kryogene Flüssigkeit haben gewöhnlich die allgemeine Konfiguration eines geschlossenen vakuumisolierten Zylinders und haben im Gebrauch eine Position mit im wesentlichen horizontaler Zylinderachse; vorzugsweise ist die oder jede einen solchen Behälter unterteilende Membran im wesentlichen eben.Transport container for cryogenic Have fluid usually the general configuration of a closed vacuum insulated Cylinder and in use have a position with essentially horizontal cylinder axis; Preferably, the or each is one such container subdividing membrane substantially flat.
Die Membran kann im wesentlichen vertikal und im wesentlichen parallel zur Zylinderachse des Behälters orientiert sein, so daß der zylindrische Behälter der Länge nach unterteilt wird. Die Membran kann vertikal mittig im Container angeordnet sein, oder die Membran kann so angeordnet sein, daß sie nicht mit der Zylinderachse zusammenfällt. Beispielsweise bei Tankwagen, die zum Transport flüssiger Luft (Luft-Gasgemische, die im wesentlichen aus Stickstoff und Sauerstoff in ähnlichen Anteilen, aber nicht notwendigerweise identisch zu den Anteilen dieser Elemente in Luft) ausgelegt sind, kann eine einzige Membran vorgesehen sein, die bezüglich der Zylinderachse versetzt ist, so daß zwei Teile geschaffen werden, wobei derjenige für flüssigen Stickstoff etwa viermal das Volumen desjenigen für flüssigen Sauerstoff hat. Eine solche Anordnung hat auch den Vorteil, das Schwerezentrum an oder nahe an der Mittelachse des Behälters zu halten, wenn die Last teilweise als Flüssigluftgemisch abgegeben worden ist.The Membrane may be substantially vertical and substantially parallel to the cylinder axis of the container be oriented, so that the cylindrical containers the length is subdivided. The membrane can be vertically centered in the container be arranged, or the membrane may be arranged so that they do not coincides with the cylinder axis. For example, in tankers that transport liquid air (Air-gas mixtures consisting essentially of nitrogen and oxygen in similar Shares, but not necessarily identical to the shares of these Elements in air), a single membrane may be provided be that concerning the cylinder axis is offset so that two parts are created, where the one for liquid Nitrogen has about four times the volume of that for liquid oxygen. A such arrangement also has the advantage of the gravity center on or close to the center axis of the container when the load has been partially released as a liquid air mixture.
Alternativ kann die Unterteilungsmembran quer zur Zylinderachse angeordnet sein. Das wäre einfacher herzustellen, da die oder jede Unterteilungsmembran eine kleinere Fläche haben würde, und ergäbe einen kürzeren Umfangsrand, der dichtend an der Innenwand des Behälters zu befestigen wäre. Darüber hinaus könnten bei einer solchen Konfiguration die Abgabemittel so angeordnet werden, daß die Rohrleitung zur Abgabe kryogener Flüssigkeit aus einem der Teile durch den die andere kryogene Flüssigkeit enthaltenden Teil verlaufen würde; dies ergibt den Vorteil eines genauen Temperaturausgleichs der beiden kryogenen Flüssigkeiten, bevor sie abgegeben werden.alternative For example, the subdivision membrane can be arranged transversely to the cylinder axis be. That would be easier because the or each subdividing membrane has a smaller size area would have, and would result a shorter one Peripheral edge sealingly against the inner wall of the container too would be secure. About that out could in such a configuration, the dispensing means are arranged so that the pipeline for the discharge of cryogenic liquid from one of the parts through the other cryogenic liquid containing part would run; this gives the advantage of accurate temperature compensation of the two cryogenic liquids, before they are delivered.
Es ist vorgesehen, daß mindestens zwei Abgabesysteme vorhanden sind, nämlich eine zur Abgabe jeder Art von enthaltener kryogener Flüssigkeit, wobei diese Systeme durch Verdrängung oder Pumpen oder Schwerkraft betrieben würden, was auf dem Fachgebiet bekannt ist. Höchst vorzugsweise würden die verschiedenen kryogenen Flüssigkeiten innerhalb des Behälters auf identischen Drücken gehalten, um eine Beanspruchung der Unterteilungsmembran zu vermeiden. Dies kann auf eine Anzahl von Wegen erreicht werden, beispielsweise durch Entlüftung, oder höchst zweckmäßigerweise durch ein gekoppeltes Drucksteuerventil, das unter der Führung eines der Behälterteile arbeitet, wie für den Fachmann bekannt ist.It is contemplated that there will be at least two delivery systems, one for dispensing any type of cryogenic liquid contained, which systems would be operated by displacement or pumping or gravity, as known in the art. Most preferably, the various cryogenic liquids within the container would be maintained at identical pressures to avoid stressing the partitioning membrane. This can be up to a number be achieved by ways, for example by venting, or most conveniently by a coupled pressure control valve, which operates under the leadership of one of the container parts, as is known in the art.

Obwohl hier unter Bezugnahme auf einen Straßentankwagen beschrieben, versteht es sich für den Fachmann leicht, daß die Prinzipien dieser Erfindung auch auf jede andere Form eines Isolierbehälters zum Transportieren oder zum Lagern kryogener Flüssigkeiten anwendbar ist. Darüberhinaus, obwohl nur ein in zwei Teile unterteilter Behälter hier besonders beschrieben worden ist, ist diese Erfindung in gleicher Weise auf Behälter anwendbar, die in drei oder mehr Teile unterteilt sind, und das grundsätzliche Konzept der Anordnung der Membrane zur Unterteilung des Behälters in verschiedene Teile, die jeweils ein Volumen haben, das grob dem Mengenanteil jedes Gases entspricht, das in einem Gasgemisch abzugeben ist, ist darauf gleichermaßen anwendbar.Even though described herein with reference to a road tanker it is for the Professional easily that the Principles of this invention to any other form of insulated container for Transportation or storage of cryogenic liquids is applicable. Furthermore, although only one container divided into two parts is particularly described here this invention is equally applicable to containers, which are divided into three or more parts, and the basic one Concept of the arrangement of the membrane for dividing the container into different parts, each having a volume roughly the Amount of each gas corresponds to deliver that in a gas mixture is, it is alike applicable.
